title: [Clinical study of healing abutment on sealing socket and preservation of the gingival natural profile in single-tooth immediate implantation].
abstract: OBJECTIVE
  To investigate the clinical results of use of healing abutment for sealing socket and preserving the gingival natural profile in single-tooth immediate implantation.
  
  
  METHODS
  The osteotomy site was prepared with pilot drill directed by the periodontal probe on palatal wall of the socket,and 31 single-implant were placed into fresh sockets with flapless surgery and filled with Bio-oss. Healing abutments were simultaneously fitted on implants and ceramic crowns fabricated three months post-operation. Scientific assessment of soft tissue contour was carried out by interdental papillae index immediately after restorations.
  
  
  RESULTS
  One implant was lost at second week after operation. The remaining 30 implants gained perfect osseointegration and the gingival natural profile was preserved completely.
  
  
  CONCLUSIONS
  Sealing socket and preserving the gingival natural profile by healing abutment is a predictable, safe and practical method with good aesthetic results in single-tooth immediate implantation.
